Compared to the first generation, this new iCARe® generation features within the Save range lower magnetic losses and within the Torque range both lower magnetic losses and higher strength.

“The main challenge today continues to be the limited distance over which an electric car can be driven”, said Sigrid Jacobs, worldwide development director for ArcelorMittal’s electrical steels. “That is why we support manufacturers of drive systems in their efforts to develop more efficient and better-performing motors by using improved materials like the new iCARe® steels.”

The second generation of iCARe® steels makes improved power density possible, compared with the first generation. This is reflected in less weight for the same motor performance, which in turn results in increased driving range.

This also applies to the many small motors on board the car, because an improved energy balance saves electricity and thereby extends the range. Sigrid Jacobs added: “The introduction of iCARe® into automobile construction allows the industry to bring more power and more driving range into the picture.”

Three steel types

There are three steel types included in the iCARe® offer. Each type is specifically designed for a typical electric automotive application:

iCARe®

Save: steels with very low losses

Ideal for the efficiency of the eletrical machine. Their key role is maximise the use of the current coming from the battery. Read more...

Torque: steels with high permeability

They achieve the highest levels of mechanical power output for a motor or current supply for a generator. Read more...

Speed: steels for high speed rotors

Specific high strength electrical steels which maintain high level of magnetic performance. They allow the machine to be more compact and have a higher power density. Read more...
